"An event of the scale of 9/11 could happen again. It won't be commercial
airlines flying into tall buildings. It's likely to take some other
form. But while we've made a lot of progress in enhancing the safety of
the United States, I don't think we are invulnerable to another attack."

"I don't think it's speculation, it's a fact that the Saudis were
significantly involved in assisting the 19 hijackers, including
financial assistance. There's a series of events that occurred in
Sarasota. There were significant ties between people doing their flight
training in Sarasota and people of a Saudi background who lived there,
and who left Sarasota to return to Saudi Arabia less than two weeks
before 9/11 -- which raises suspicion that maybe somebody tipped them
off."
